Service Tunnel Ventilation
Service Tunnel Ventilation
(OP)
I have an electrical service tunnel about 500' long with an 8'x8' cross section. Ozone is not an issue, but Radon might be.
Is there a standard for number of air changes that should be used to determine the fan required? With or without radon?
If radon is present, is there a requirement for treating the 'radon laden' air?

d(Mal)/dt= d(Mcg)/dt x Mat / Mctf
where
d(Mcg)/dt=mass rate of radon or other contaminants
generated
Mat=mass of air in the tunnel
Mctf= mass of radon or other contaminants
acceptable within tunnel-dont forget factor
of safety when using ACGHI limits
d(Mal)/dt=mass rate of air flow in tunnel
